Product Overview

The HM-SVOC from HM Instruments is a handheld photoionization detector for monitoring volatile organic compounds. A built-in adjustable pump draws the gas sample, and the color display shows concentration and a real-time trend curve.

Key Features

PID sensing supports VOC concentration monitoring with range-dependent resolution.
Adjustable pump flow and a sampling probe support gas collection.
Audible, visual and display alarms show gas and instrument status.
Data logging, wireless communication and an external Bluetooth printer are configuration-dependent options.
Chinese and English display switching and Micro-USB charging are supported.

Applications

Use for VOC checks in workshops, facility boundaries, emission-source investigations and emergency environmental monitoring. Suitable sectors include petroleum, petrochemicals, chemicals, environmental protection, wastewater treatment and research. Select the PID range and sampling accessories for the gas mixture and sampling conditions.

Operation and Support

Select the VOC range and resolution for the intended concentration and arrange appropriate calibration gas and sampling accessories. Keep moisture noncondensing at the instrument; high-temperature, humid or dusty gas sampling requires suitable sampling and filtration accessories. Optional multi-gas sensing, wireless links, touch operation and printing depend on the configuration ordered.
